So, I just got a new MacBook Pro and everything seems to be working fine except that I cannot send nor receive SMS text messages through iMessages. Works fine on my iPhone, so I'm sure the numbers are correct. I've turned iMessage on my phone off then back on hoping that it would repopulate my phone numbers in Contacts, but that didn't solve the problem. I also have a Mac Pro in my office and a Hackintosh desktop and neither of them have this problem. Any suggestions?
